Brat: Robe of OfferingThe tartan is also a religious and spiritual garment. In the sacred text of Ireland & Scotland called the Leabhar Breac eight color tartan cloaks known as brat were worn by holy priests called Druids: yellow, blue, white, green, brown, red, black & purple. When Christianity came the vestment of priests was transformed into a tartan with eight colors, known as The Robe of Offerings. Eight colors indicated that while officiating the priest was superior to the king, who wore seven colors. Sacred vessels of the Eucharist were covered with two veils, the inner of pure white linen, and the outer of checkered silk called a siric brec.
